Title: Automatic setting of injection measuring stroke and device therefor
Inventor: YAMASHITA NORIO
IPC: B29C45/76
Filed: 1988-10-04
Abstract: PURPOSE:To set up automatically the optimum measuring stroke for one time molding production after an exchange of molds, by a method wherein set up parameters of a measuring stroke are set up as a moving speed of a screw, pressure and a desired remaining quantity of resin within a cylinder at the time of casting of the resin. CONSTITUTION:When resin is filled away into a mold 5, a moving speed of a screw 3 is reduced and at a point of time when the moving speed arrives at a set up speed V1, a solenoid proportional pressure servovalve 8 is controlled so that an injection process is shifted to pressure control injection from speed control injection and pressure to be applied to an injection cylinder 2 becomes preset pressure P0. At a point of time when the moving speed becomes an established speed Vo and under, an injection process completion signal is put out through a comparator. In a measuring stroke setting apparatus, a shifting stroke of the screw 3 is obtained through positional information applied to the measuring stroke setting apparatus and added to a desired remaining quantity stroke l1 established in a remaining quantity setting apparatus. When a shifting stroke of the screw 3 is l2, a measuring stroke setting apparatus informs a stroke setting controller of the sum of l1 same and the desired remaining quantity stroke l1, that is, the l1+l2 as the optimum measuring stroke.
